EA FAST EIBAR 380(9MM)

Hey everyone. I have recently been given an EA Fast Eibar 380...Now I know that some consider this a junk gun, but it was my father-in-laws and I would really like to get it fixed. It is missing some parts. the left grip that appears to hold the transfer bar in place, the entire extractor (pin, spring, etc) and possible a pin that goes through the top of the slide. I have tried Numrich and they were able to get some parts..couple springs..pins...ejector and pin, but they are sold out of the rest and Bob's gun parts no longer can get these...Any ideas??
